Unable to open url to the Mac App Store in an iOS app launched on Mac with Apple Silicon

Question

I have this code to open a link to the App Store for the user to write a review:

guard var urlComponents = URLComponents(string: "https://apps.apple.com/app/anysub/id1615546730") else { return }
urlComponents.queryItems = [URLQueryItem(name: "action", value: "write-review")]

if let writeReviewUrl = urlComponents.url {
    if UIApplication.shared.canOpenURL(writeReviewUrl) {
        UIApplication.shared.open(writeReviewUrl)
    }
}

For some reason my app crashes when I open this link. It opens in Safari, but the app crashes. The most interesting thing is that if I replace the url with any other non App Store link, everything works fine.

I also tried to change the App Store link to macappstore://itunes.apple.com/app/id1615546730 and it doesn't help.

P.S. It's calling from the main thread.

To enable a user to initiate a review as a result of an action in the UI use a deep link to the App Store page for your app with the query parameter action=write-review appended to the URL.
